Hello....My friend just bought either a 1956 0r 57 chevy 3100 truck and need to find out what year it is. I see the blue tag on the driver side door jam and lists a trim number and paint code but no VIN number. Where is the VIN number located on these trucks? Please don't tell me it's on the frame as it sits on a 1977 truck chassis. I did see on the lower left corner of the tage is printed 56 and is not stamped like the other numbers. Any help would be great. Thanks!!
